MICA allows to detect alicyclobacillus bacteria in 24 hours

Alicyclobacillus detection & enumeration

Results in 24 hours, in CFU (Colony Forming Units)

A new improved way to count Alicyclobacillus in beverageS

Alicyclobacillus acidoterrestris, also known as Thermophilic Acidophilic Bacteria (TAB) is a cause of microbial spoilage in fruit juices, juice related products or syrups. Its inconspicuous nature can lead to large-scale spoilage incidents with serious consequences for the beverage industry. Control and detection of the organism at its very early stage of microcolony in the manufacturing process is therefore crucial.

With Diamidex technology and MICA equipment, it is now possible to detect and count them in 3 minutes, after just 24 hours of incubation on Petri dishes.

Why choosing MICA Alicyclobacillus?

Results reading of agar in 3 minutes


.An incubation reduced to 24 hours compared to 5 days with the traditional method – Results rendering in 3 minutes


IFU method No. 12:2019 standards compliant – Equivalent results with the standard agar plate for Alicyclobacillus acidoterrestris presence/absence – Exact same procedure with one reactive added between membrane and Agar.


Detection and counting from 1 CFU* of Alicyclobacillus acidoterrestris  & Alicyclobacillus spp. per membrane – Same detection level (1 CFU*) wether samples are 1, 10 or 100 mL.

* Colony Forming Units


An ultra competitive price with degressive rates – Non technical method.

Bacteria information

  • Alicyclobacillus acidoterrestris is a non-pathogenic bacterium. It is an acid tolerant thermophylic microorganism that produce endospores. It was first isolated from soil.
  • As a spore, it is strongly heat resistant and capable to survive the usual heat processes and pasteurization used in the fruit juice and beverrage industry.
  • Its presence in consumer packaged products has been reported to cause flavour and odour spoilage problems described as “Antiseptic” or “Hammy”.
  • MICA Alicyclobacillus allows to detect many strains : A. acidoterrestris, A. herbarius, A. hesperidum, A. acidiphilus.

MICA, the first smart microcolony counter on the market

An extreme sensitivity allowing to detect microorganisms at their early culturable stage

Thanks to an unmatched optical resolution among colonies counters, MICA is capable of detecting and counting microorganisms at their microcolony stage.

  • Automated Smartscan: 70 shots per membrane
  • Fluorescence detection and bright field

Integrated safety and traceability

MICA includes a software according to the targeted microorganism. The use of MICA is 21 CFR Part 11 compliant. The analysis history is accessible, and all data are exportable and can be integrated into a LIMS or CRM system making of MICA an essential decision support tool.


A semi-automatic solution, easy to use and to implement

Designed as a turnkey solution, MICA is easy to use and to implement, by all technicians. The operator is guided step-by-step through a simplified protocol according to the targeted microorganism. The automatic counting of microcolonies ensures fewer uninterpretable results than traditional culture method, faster

A smart counter easily integrated into a LEAN management system

MICA has been specifically created to meet laboratories’ and industrials’ needs to improve their productivity. Technician time savings are made thanks to a simplified protocol, including function such as repeatability of results & readings. Results are released faster to the client allowing a better microbiological workflow.
